The function is $\"\"$ .

Compare the function $\"\"$ with $\"\"$ .

a = 1, b = 4, c = 0 and Period = $\"\"$ .

Two consecutive vertical asymptotes can be found by solving the equations $\"\"$ and $\"\"$ .

$\"\"$ and $\"\"$

The that two consecutive vertical asymptotes occur at $\"\"$ and $\"\"$ .

The interval $\"\"$ corresponds to one cycle of the graph. Dividing this interval into four equal parts produces the key points.

one fourth of part is $\"\"$ .

The x - coordinates of the five key points are

Between these two asymptotes, plot a few points, including the intercept, as shown in the table.

First plot the asymptotes.

The midpoint between two consecutive vertical asymptotes is an x - intercept of the graph. The period of the function $\"\"$ is the distance between two consecutive vertical asymptotes. The amplitude of a tangent function is not defined.

After plotting the asymptotes and the x - intercept, plot a few additional points between the two asymptotes and sketch one cycle. Finally, sketch one or two additional cycles to the left and right.

Plot these five points and fill in the graph of the tangent function as shown in Figure.
